POSTAGE METER.

Application filed July 12, 1922. Serial No. 574,427.

This invention relates to means for registering the number of operations of a machine, and is particularly designed for use in the so-called postage meter mach nes of the type shown in my Patents #127 3,793 dated July 23, 1918, Reissue #14916 dated July 13, 1920, agnd #1,370,668 dated March 8 1921.

' ,Such machines are designed for use by 10 persons, firms, or corporations having a large number of letters or packages to mail, to enable such users of the mail to buy any desired amount of prepaid postage from the Government, and print such amount of postage, from time to time, in any quantities and amouts that they desire, until the total amount of postage for which they paid is exhausted, whereupon the machine will become automatically lockedsothat no further stamp s ca'n be printed, thereby.

The present invention provides a simple novel detachable meter equipped with a counter, and means for registering thetotal amount of the various settings or chargings of the meter. Like the Pitney postage meter now in use (Patent #1,370,668 March 8, 1921) the meter embodying the present invention can .be charged or set for use and then used as desired in applying 0 or printing ostage up to the predetermined amount, and will then be locked against further operation when that amount is exhausted. I

The particular object of this invention is to provide a meter which will register the performance of a postage meter machine, either by registering the exact number of impressions of a die of fixed denomination, or registering the amount in dollars and cents of that type of postage meter machine which prints stamps of varying denominations. The construction of the meter is essentially the same in either case, the differ ence being that a meter of this construction applied to the former type of postage meter machine, will look when the full number of impressions has been made, and the numerals at the sight opening will show an abstract number representing the number .50 of impressions used; but when applied to a machine of theflatter type the numerals at the sight opening will indicate dollars and cents, and the meter will lock when the whole number of dollars is exhausted; and

' .which, however,

, may leave an unused balance in cents, which unused fraction of a dollar will be added to the amount purchased at the next setting of the meter, and not lost.

Other objects and advantages of the invention will be hereinafter set forth and I will explain the invention with reference to the accompanying drawings which illustrate one practical embodiment of the invention,

changes in form, construction and combinations of parts wlthin the S00 e of the lnvention. An understanding 0 said machine will enable others to adopt and use the invention for various purposes within the scope of the claims, which set forth the essentials of the invention and the novel features of construction and novel combinations of parts for all of which protection is desired.

In the drawings I have shown the meter and only such parts of a machine with which operation such as shown and described in my Patent #1,370,668. Also preferably the printing mechanism is so constructed that it will not function, if for any reason, the said meter pin is prevented fromprojecting into the meter at each operation of the printer.

Fig. 22 is an enlarged detail sectional view of mechanism for locking the meter on the printer.

Fig. 23 is a detail view showing parts of such parts in section.

As shown in the accompanying drawings the meter comprises a hollow base member 1 upon which is mounted a casing 2 enclosing the counting or registering mechanism. The base 1 is formed of a casting approximately rectangular and closed at top and each end but open at bottom; the bottom however being closed after the parts are assembled by a slidable plate 4, which when closed is secured by a spring actuated catch 5 as shown in Fig. 4, so that if the'plate is once put in place it can not be removed, as this catch 5 is inaccessible and when it locks the plate can not be withdrawn, except by first drilling through the plate.

The casing 2 may also be cast and is closed at top, sides and ends and secured to the top of the base by screws 2 which screws are inaccessible when plate 4 is in place. One end of the casing 2 has an opening which is fitted to and closed by a projection 1 on the upper side of the base and preferably formed integral therewith as shown, so that access cannot be had to the, interior of the casing except through a "door 2 which is provided at one, side thereof, and is secured when closed, by a lock 2 preferably a Y ale lock; so'that unauthorized access to the interior of the casin or meddling with the mechanism are preve ted. Access to the lock2 ma be further revented by a cover plate 2 w ich can be astened by'an ordinary seal 2", as indicated in Figs. 1 and 2, and would have to be broken oif before a key could be insert ed in the look; so meddling with the lock by an unauthorized person would be immedi ately detected.

' J ournaled in a bore in the part 1 of the base, or in the end of the casing 2, is a shaft 7 to the outerend of which is securely fastened a coupling member 8, hereinafter referred to, and on the inner end ofshaft T.

within the casing 2, is fixed a pair of spaced pinions 9 and 9; which may be formed intogral and connected by a suitable hub as indicated in the drawings. The inner gear 9 meshes with the gear 50 (see Figs. 3 and 4) attached to the unit wheels 50 of the counting mechanism in the casing as hereinafter described, said counting mechanism being driven by the rotation of the shaft 7.

lVithin the casing 2 is a frame 3 carrying the registering or counting mechanisms hereinafter referred to. This frame 3 is spaced from the top of the base 1 by distance pieces 3 and fastened thereto by screws 3 which are inaccessible when the plate 4 is in place.

The counting mechanism is preferably of the geared type, that is the motion of one of its numeral wheels is'communicated to the next numeral wheel of higher denomination by means of intermittently operated gears. The unit wheel 50 is the prime mover of the series. None of the wheels can be turned independently, but each is moved in regular order of progression by means of its gear connection with the unit wheel.

As shown in Figs. 38 a series of such numeral wheels 50, 51, 52, 53, 54 are loosely mounted on a spindle 60, supported in the ends of the frame 3. unit wheel of the series and has connected therewith a spur gear 50, and a one tooth gear 50", securely fastened together, and acting as one piece. The gear 50 of the unit wheel 50 meshes with the spur gear 9 on the drive shaft 7 of the meter, consequently any motion of this shaft 7 (which is coupled by coupling 8 to the mechanism to which the meter is applied) will be communicated to the unit wheel 50, and therefrom to the other numeral wheels in order.

In the example shown there are five numeral wheels50, 51, 52, 53, 54, in the main counting or re istering mechanism. .Vheel 50 being the units or cents wheel;- 51 the tens wheel; 52 the hundreds or dollar wheel; 53 the tens of dollars wheel; and 54 the hundreds of dollars wheel, as hereinafter explained. Each of these wheels is provided with a spur gear 50 and one tooth gear 50 either formed integral therewith or secured thereto so that all act as one; similar parts being similarly lettered in the drawings. 7

Parallel to spindle is a spindle 61 set in the frame 3. Upon this spindle 61 are loosely mounted small pinions 62 each having IOU The wheel 50 is the p ten teeth but each alternate tooth is cut or milled away at one end as at 62 forming stops (see Fig. 3). One of these intermediate pinions 62 is placed on spindle 60 adjacent and between each pair of adjacent numeral wheels 5051; 51-52; 53-54, etc., in such a way tha the complete toothed portion of pinion 62 wi l mesh with the spur. gear 50 of the related numeral wheel of higher denomination, while its stop 62 will engage the related one tooth gear 50 of the related numeral wheel of lower denomination (see Fig. 3).

Each one tooth gear 5O will move its related gear 62, but once during one revolution; and as there are 5 stops in each ten tooth gear 62, such gear 62 is advanced two teeth by and for each revolution of its related gear 50, and as each gear 50 has 20 teeth it follows that any numeral wheel of higher denomination in the series will be advanced 1/10 of a revolution for each revolution of the numeral wheel of next lower denomination.

' Thus the numeral wheels will be properly operated in; sequence as is required in any consecutive numbering or registering device, and I have provided novel means for locking said registering mechanism against further operation when it has completed its full count, as 1' will be hereinafter explained. The numeral wheels and their carryover devices above described are of well known construction and do not require more detailed explanation or illustration. Further, while I prefer to use this type and construction of registering wheels and carryover devices the invention is not limited thereto, and any other suitable kind of registering wheels and carryover devices could be used.

If in a counter containing 3 numeral wheels it is desired to'subtract instead of to add, the wheels should be set tostart at zero (000) which in reality is 1000 as the next number in the series is 999 and when so set it will subtract consecutively, a unit at a time, till 001 is reached; then the next count (decrease of 1) will bring all the wheels back to zero again (000) which is actual zero this time, as 1000 has'been subtracted from the original count.. I have therefore provided means for automatically locking the meter at this oint; and when so locked the numeral w eels cannot be shifted until the locking mechanism has been reset by hand. The object of this locking and resetting is hereinafter v explained.

*The particular meter illustrated in the drawings submitted is designed for use on a machine which prints postage stamps of denominations varying from 1 to $1.00 consequently the registering mechanism or counter in this meter should be made to lock when the'3 numeral wheels (52, 53, 54) indicating dollars come to their zero (0) positions disregarding the positions of thetwo wheels 50, 51 which indicate cents.

To each numeral wheel 52, 53, 54, a disk 50 is attached, and preferably placed at the left hand side of such Wheel, asshown in Figs. ,4 and 5. Each disk 52, 53, 54, has a radial slot 54 in its periphery to admit the related tooth (14, 14, 14) of a locking member 14 hereinafter described.

The locking member 14 is pivoted at one end on a rod 14 between two upwardly proj ecting lugs on the floor of the counter frame 3 (see Figs. 3, 6) and the end of said member is normally pushed upward by springs 14 set into sockets in the floor of the frame 3. The outer or free end of this locking member 14 is provided with a series of upwardly projecting teeth 14, 14, 14 (see Figs. 4 and 6) respectively positioned so as to engage with the disks, 52, 53, 54, attached to the respective numeral wheels 52, 53, 54, (see Fig. 4). Formed on or attached to one side of the locking member 14 is a plate 14 (Figs. 3 and 5) the outer end 14 of this plate projecting towards the door 2 of the meter casing and forms a convenient handle by which the locking member 14 can be depressed by hand, to disengage its teeth from the .disks, when resetting the meter.

Said plate 14 also has a downwardly ei;

tending portion 14 which extends through a slot in the floor of the counter frame 3 into the space between the floor of the counter frame 3 and the top of the base 1 to arrest the meter locking lever 6 hereinafter referred to. I

The teeth 14, 14, 14 of the locking member 14 vary in length relative to the disks 54, 53, and 52 with which they'make engagement. The tooth 14 which engages the disk 54 will bear on disk 54 and hold teeth 14, and 14 clear of their disks 53 and 52 (Fig. 4) until tooth 14, enters the slot 54 in di'sk.54, then the tooth 14, the

,next in length, will bear on the disk 53,

and holding tooth 14 clear of disk 52 until tooth 14 enters the. slot in disk 53; then the tooth 14bears on disk 52 until it enters the slot in disk52. Thereupon (there being no further obstruction) the three teeth 14, 14 and 14 enter their respective slots to the'full depth and lock the respective numeral Wheels at zero;

When the three numeral Wheels all show zero atthe sight opening the teeth 14, 14, 14 of the locking member 14 are all seated in the slotsin the disks 54, 53, and 52 respectively. I

When the meter is to be reset or char ed the locking member 14 is pulled down y hand, to disengage the teeth from the. disks and release the wheels for further action; and as the numeral wheels 54, 53,-

member 14 would spring back into engagement with the slots 54, 53 and 52 again, upon releasing the hand pressure on 14, if no obstacle to the teeth 14*, etc., entering the slots intervened; I therefore provide means to prevent the locking member reengaging the numeral wheels after they are released thereby, until the meter has again performed its full cycle of operations. For this purpose I provide a shield (Figs. 3, 4, and 9-12) which. in the form of a ring, is slidably mounted on the unit of which the num eral wheel 54 forms a part.

Figs. 9 to 12 show in detail the construction of the unit of which wheel 54 forms a part, and which unit consists of the spur gear 54, numeral wheel 54, disk 54, sleeve 54 and a one-tooth gear 54 all of which are formed or rigidly fastened together and operate as one piece. The sleeve 54 has an annular flange 54 upon the periphery of which a figure 1 is engraved or marked in line with the 0 mark on the wheel 54, (see Figs. 9-11). A ring is loosely mounted on sleeve 54 between flange 54 and disk 54, said ring being preferably exteriorly knurled to facilitate its being turned by hand. This ring has an annular portion 55 on its side surrounding the periphery of flange 54, and in this flange is a notch 55 to permit the numeral 1 on flange 54 to be exposed to view when the ring is turned to bring the notch over the numeral, as in Fig. The ring 55 also has a lug 55 (see Fig. 0) on its side opposite the part 55 which lug projects over the periphery of the disk 5%. this lug 55 being large enough to manplit 'ly cover the slot 54 in the disk 54", when in register therewith (Fig. 14) leaving the rest of the periphery of disk 54" exposed. (See Fig. 12.) A short segmental slot 55" is formed in the inner side of the sing 55, see .l ig. 15, and is engaged by a pin 54", projecting from the sleeve 54*. This in and slot limit the extent of rotatorial mowgment of the ring 55 on sleeve 54 so it can be moved just sufficient to eauseiug- 5 5" to "over and uncover the slot 54, and IlOlCll 55 to expose.

or hide the numeral l on flange 54. The notch 55 and the lug 55 are so positioned with relation to the disk 54 and flange 54* that the numeral 1 on the flange is only exposed to view when the lug 55 covers the slot 5%.

Fig. 11 shows the appearance of the hundI'Bti d llar unit looking down from the dial side of the meter case, just before charging or setting the meter, at which time the numeral 1 on flange 54 is hidden by the rim 55 of the ring 55. Then the meter is charged or set. The numeral 1 is exposed through the notch 55 as in Fig. 9.

Nhen the wheel 54 is revolved 1/10 of a revolution the friction of the ring 55 on the 'bly moving the lug sleeve 54 may not cause ring 55 to turn in slot 55 (F ig. 15) contacting with the end wall of the slot 55 in ring 55, and forci- 55" out of the way of the tooth 14*, and tooth 14 then contacts directly with the periphery of the disk 54 (see Fig. 18) and even if the ring 55 (which now floats loosely on the part 54 should be moved by vibration or other cause, the lug 55 cannot again come between the flange 54 and the end of the tooth 14.

Fig. 14 shows the lug 55 covering the slot 54 in disk 54 with tooth 14 pressing upon it. ,Fig. 18 shows the disk near the completion of a revolution of the numeral wheel, and the lug 55 fallen or jarred down so that it again covers the slot 54. Fig. 19 shows the disk 54 still further advanced and illustrates how the point of tooth 14 will push the lug 55 out of the way until it can enter the slot as illustrated in Fig. 17.

The counter locking dem'ces.

.or tampering with the numeral wheels of the counter, or improper rotation of the shaft 7, a catch 11 is pivoted at ll on the inside back wall of the meter and is normally urged into engagement with the teeth of the gear 9 by a spring 11 and is only prevented from taking this {position by reason of its lower arm 11 resting on the shutter lever 6- (Fig 8) hereinafter referred to. This catch 11 engaging gear 9 prevents its retation in one direction while pawl 10 prevents rotation of gear 9 in the opposite direction. Catch 11 is not designed to prevent shaft 7 from being turned when meter is removed from the machine, but is a part of the counter locking device, and is only engaged with gear 9 when the numeral wheels 52, 53 and 54 are locked at zero. Catch 12 is the one that engages 9 each time meter is removed.

For the purpose of disengaging the latch 11 from the gearQ when charging the meter (as described later on) a two armed lever 13 (see Figs. 5 and 8) is pivoted on the floor of the counter frame at 13 and. provided with I lltlll tion:of levei 6yto register'w'ith a hole 1" a spring 13 which holds the short arm 13- of the lever normally tightly against an ad'- jacent part of the counter frame 3; and the long arm 13 of the lever projects beneath the counter wheels, toward the door of the case 2. WVhen arm 13 is moved toward the right (Fig. 5) the short arm 13 is moved away.from the frame 3 and will engage a pin 11 attached to the catch 11, and thereby move catch -11 out of engagement with the gear 9*. p

- Below the counter frame 3, in the space provided by the distance pieces 3Lisa twoarmed lever 6, (see Figs. 6 and 8) pivoted" drilled in the inner wall of base 1. When lever 6 is oscillated, hole 6 in head 6 is "alternately moved into and out of register with hole 1 and therefore cause head G to alternately obstruct and allow free to a pin 15 (see Figs. 4 and 6) into hole 1 and endeavoring to enter the hole 6 in the head 6, said head thus constituting a shutter for the hole 1. I

The arm 6 of the lever 6 extends at a right angle to the arm 6 toward the door of the meter case 2, its extreme end (see Fig. 5) forming a convenient handle for moving it, when charging the meter. To this arm 6 is connected the spring 6 which'urges it toward the left, but is normally prevented from so moving it by the interposition of the projection 14 on the locking member 14. (See Figs. 4 and 6.)

Then the shutter lever that its short arm 6 rests against the projection 14 of locking member 14, the hole 6 in the-head 6 is directly in line with the hole 1? in the base 1; so that the pin 15 see Figs. 4 and 6) can enter hole 6 If however, the projection 14 is removed as by the raising of the locking member 14, then the spring 6 will cause the shutter lever 6 to V 6 is so positioned rock on its pivot 6 and the holes 6 andlfi.

will not registerwand ,pin. 15- cannotenter hole6 and the meter cannot then be effectively operated until reset.

The total regz'eter. I

on the spindle and receiving their motion directly from the last or highest order numeral wheel of the above described counter. In forms of the constructionshown the total register is in fact a duplicate ef, parts of the first counter, but the total register numeral wheels are arranged to add instead of subtract, and the total register shows the sum of the dilferent settings of the subtracting counter. I

As shown in the drawing the numeral wheel 56 has a spur gear 50'- having one tooth 50 adapted to coact with an intermediate pinion 62 which is operated by a one tooth gear 54 on the sleeve 54?; and motion is transmitted from the unit carrying wheel 54 to the wheel 56 and from the latter to wheel 57 by the same meansand in the same manner that motion is transmitted from a numeral wheel of lower denomination to the numeral wheel of the next higher denomination in the subtracting counter as above descibed; and similar parts being similarly lettered in the drawings, it is unnecessary to enter into a detailed description of the construction and operation of the total register. The numpassage pro ect1ng bers on the numeral wheels in the total register however are arranged reversely to the numbers on the wheels in the subtracting counter so that while the latter starts at the highest number (1000) and subtracts until the zero is reached, the total register will start at zero and add until its highest numher is reached.

As above stated and as shown the units wheel 56 of the total register is directly geared to or driven by the hundreds dollar wheel of the subtracting counter. Therefore as it is directly geared to the hundreds dollar wheel the numeral wheel 56 makes revolution to one of the wheel 54, and as the subtracting counter (in the construction shown) has to be reset for each $1000.00 it follows that the total register will register or add one unit thereon every time the subtracting counter completes its full quota of operations, at which time the meter will become locked against further effective operations until it. is reset or charged. In

practice "the meter is charged for a definite amount at each setting ($1,000.00 in the meter shown). Therefore, the reading of the total register will show the number of times the meter has been charged or reset -and this tetal multiplied by 1000 (in the meter shown) will show the total amount of postage in dollars which the owner of the meter has paid for.

Operation of the counter and register.

As stated, the meter is designed to be removably attached to a machine to register the number of operations thereof and the meter shown is particularly adapted to be attached to a machine of the type shown in my patents #1,273,793 and #1,370,668, or

other machines of like general character. The particular machine to which this meter is applied is not shown herein but it forms no part of the present invention and will not be described or illustrated herein except such parts thereof as may come in operative connection with the meter when the latter is properly positioned in the machine. It will suffice to state that such machine is provided with a printing mechanism, with a meter pin 15' and driving connection, and a lock adapted to function as hereinafter described.

When the meter is used in connection'with such a machine the meter is supposed to be taken to the Post Office Department and (if the meter has a subtracting counter as shown) the owner purchases one thousand dollars worth of postage and the postofiice official will set the subtracting meter to show the full amount of $1000 at the sight opening. The postofiice oflicial then seals the meter and when so set the meter can be replaced on the machine and the latter operated, as desired, until practically the, full amount of $1000postage has been used by printing stamps to that amount by successive operations of the machine- The subtracting counter cannot be operated unless the meter is in place on the machine, as when removed therefrom the meter is automatically looked as hereinafter-explained. When the meter is in place on the machine, the unit wheel of the subtracting counter. will be operated for each operationof-the machine. Of course it is obvious that if it is desired to have the meter set for a larger amount of postage more numeral wheels would have to be used in the subtractingcounter. If it is desired to have a less amount of postage sold for each setting, less numeral wheels could be employed in the subtracting counter. Inthe example shown five numeral wheels are used in the subtracting counter and therefore $1000 worth of postage is presumed to be purchased at each setting of the meter. In the example shown the counter is of the geared type and its numeral wheels cannot be moved independently either by accident or design. This capacity is governed by the number of figure wheels in the counter, each additional wheel after the first increasing the capacity ten times; for instance, 5 wheels As the five ciphers turn over the five 9s v For instance, it the mlTegister l-las twg wheels and the dollars and cents counter has five wheels, and the meter has been set or recharged 23 times it would show that the mailer had paid $23,000 to date, and still had to his credit in the meter whatever amount might be shown on the subtracting counter. In otherwords, the total register would have a capacity of showing up to 99 separate and successive'purchases of $1000 worth of postage at each purchase.

It theisubtracting or counter had only 4 wheels two of them representing cents, and the total register had two wheels and read 23 it would mean that the meter had been reset 23 times for the capacity of $100 e'achthis would be the same as saying the mailer had paid for $2300 worth of postage to date with whatever balance might be indicated. In other words, the total register not only indicates the number of times themeter has been set but also the total amount in dollars of the postage paid for.

With a geared counter and suitable connections it would be possible to print any denomination'ot stamp desiredwith greater ease and positive action than with a ratchet counter of either the external or internal type of movement and subtract the amount of postage used at each operation from the total appearing at the sight opening of the subtracting counter.

Operation of charging or setting the meter. V The meter is originally set at zero; the

numeral wheels all showing 00 at the total sight opening and 000.00 at the subtracting counter (dollar and cents) would have a maximum capacity of $999.99nsighiopening. The teeth of the locking but by utilizing the 5 ciphers as they come into position the real capacit of the counter is equivalent to $1000.00-t e figure 1 not appearing. To provide for this contingency the figure 1 is engraved at a certain point on the periphery of the extension. or hub of the last wheel 54 of the counter and which automatically becomes visible upon moving the lug 55 against. which the last tooth 14 (to the left on the locking comb rests, down each time t e meter is recharged.

closed by the shutter lever head 6* and the dollars and cents catch 11 engaged with-the gear 9; in other Words, the meter and counters will be eflectually locked against operation.

Upon opening the door 2 of the case 2, the three levers 13 6", andv 14 and the knurled ring 55, are accessible. The lever 13 is then moved to the right causing its show 1000.00 at the sight opening.

= of the slots in their related disks.

the slots in the disks of numeral wheels 54,

53, 52; and this downward movement of lockmg member 14 causes its projection 14 to extend below the counter frame 3 and prevents the lever 6 from being returned to normal position by its spring 6 Finally the knurled ring is turned so as to cause lug 55 to cover the slot 54 in the disk 54 of wheel 54 and prevent the re-entry of the tooth 14 of the locking member 14 into said slot and hold the locking member depressed against the action of its springs 14 and the teeth 14* and 14 will also be held clear The turning of the ring 55, to cause lug 55 to cover the slot 54", moves the notch 55 to position to expose the 1 engraved on the periphery of the flange 54 (see Fig. 9). The sub tracting counter numeral wheels will now (See Fig. 20). This figure 1 appearing at the sight opening (see Fig. 1) is prooil. that the meter has been properly set; it also shows that $1000 in postage has been paid for and can be used instead of leaving it to be inferred, as would have to be the case if only 000.00 appeared at the sight opening of the subtracting counter after the setting 'or'charging; the dial would also read exactly the same both before and after charging, if it were not for the introduction of the extra figure 1 just mentioned and as shown in Figs, 1, 9, and 11.

The automatic locking of the meter.

When the meter is o erated the first unit of one cent will su tract 1 from the $1000.00 shown on the dial. This means that all five figure wheels will be moved 1/10 revolution and will read 999.99 (see Fig. 21) the flanges 54 being connected with the numeral wheel 54, will also revolve 1/10 revolution moving the figure 1 engraved upon it, out of sight on the dial. The unit wheel 56 of the total register will also be moved 1/10 revolution hiding the 0 and bringing the 1 into View on the dial. The reading at the sight opening ofthe total register will then be 01 and at the sight opening of the subtracting counter will be 999.99 (see Fig. 21).

When the numeral wheel 54 has been turned until, the tooth 14 enters the slot 54 the next tooth 14 of the locking member 14 rests on the periphery of the disk 54of numeral wheel 53 and will enter the slot 53 therein the next time it registers therewith, which will be when the subtracting counter shows 009.99.

The last tooth 14 will now rest on disk 52 and when the slot 52 therein registers with the tooth 14, which will happen when the dial reads 000.99 or less all obstructions will be removed and all the teeth 14*, 14, and 14 will enter their respective slots to the full depth and the locking member 14 will rise to its limit, drawing up with it the downwardly projecting lug 14*.

When the lug 14 is drawn up out of the in the hole 6 of the head.6 of shutter lever arm (3 of said lever, said pin 15 as hereinafter exp ained, being only withdrawn from the meter at the completion of the then occurring printing operation of the machine to which the meter is attached. as pin 15 is Withdrawn, the lever 6 is moved by spring 6 throwing the hole 6 out of register with the hole 1 in the end wall of the meter, so that pin 15 cannot again reenter it, Also when lever 6 is thus rocked, the lower arm 11 of catch 11, which was upheld by the lever arm 6 is released, and the catch is rocked by its spring 11 and its upper arm 11 brought into engagement with the gear wheel 9, thus locking the drive shaft 7 of the meter, and the hole 1 being closed, the meter pin 15 cannot enter again; and until it can again enter the related printing mechanism (or other operative mechanism) to which the meter is applied, is also rendered inefiective until the meter is removed, reset, and replaced therein.

But as soon may be detached from the printing meclr anism at a time when it is charged, in which event the drive shaft 7 could be turned forwardly by hand, by means of the coupling 8, although it could not be turned backwards and made to undo the count it had already made, because the pawl 10 with in the meter prevents any backward movement of the driving shaft 7; but shaft 7 might be turned in a forward direction, be- \cause the catch 11 is not then meshed with gear 9 unless and until the subtracting counter has completed its cycle of operations,.as above described. It is also desirable to provide such connection between the meter and the printer or machine with which the meter is used, as will positively prevent such machine from being effectively used, unless the meter is properly connected with it to register its operations. To meet these two requirements the printer (or machine with which the meter is used) is provided with a key operated lock, the key to which is contained within, and is inseparable from, the meter and necessitates the proper placing of the meter in or on the machine in order to release the printer for operation.

As above stated the meter is designed'to be removably attached to a machine to register the number of operations thereof; and

5 the meter shown is particularly adapted to end first, until the coupling 8, on the shaft 7, meshes with a coupling 102 on a shaft 102 of the printing mechanism (see Fig. 4).

As shown in Figs. 4 and 22 a cylindric lock casing 101 is attached to a part lOt) of the printing mechanism or machine and at the point where the meter is to be placed in said machine, and projecting into the space to be occupied by the meter. In casing 101 is a cylinder lock 101 (Figs. 4 and 22) which is completely closed exteriorly except the key hole, by the casing 101 which is securely fastened to the frame 100 in such manner that the fastenings will be inaccessible. The functions of this printer lock are (1) to secure the meter pin 15 in its inner position; and (2) to secure the.

meter in position on the printer. And these functions are performed alternately, that is, when' the meter pin is secured, the meter is released; and when the meter is secured the meter pin is released. The arrangement of the bolts of this lock are not part of the present invention and are merely indicated in the drawings sufii'ciently in connection with the description to impart a'clear understanding thereof.

A hole 1 is bored through the end Wall 1 of the meter (Figs. 4, 22, and 23) a: admit the projecting lock casing 101, which OHS-1 ing enters said hole in the meter whenthe latter is pushed into proper operative position on the machine.

Another hole 1 is bored in'the front wall of the meter base in line with hole 1 but its axis is 3/16 of an intzh below the axis of hole 1 A key shaft 16 is placed in the base, one

end thereof passing through the hole 1 and its other end extending toward the hole 1 and is slidably mounted in a sleeve 19 which is slidably supported in a bracket 1 in the base, as shown in Figs. 4, 6, 22. The rod 16 is keyed to the sleeve, as at 16 and a lock key 18 is fastened to the end of rod 16 and projects into the bore of the sleeve, as indicated in Fig. 4 when the meter is removed from the machine. The sleeve is therefore forced to turn with the rod 16 though it may move thereon in the direction of its axis. The part 1 acts as an alignment guide, and support for the sleeve 19, and rod 16. On the outer end of sleeve 19 is an eccentric circular cam 19, the center of which is 3/16 of an inch from the center of the sleeve. In one position of the sleeve the cam will be in line with the hole 1 which it i)s designed to enter. (See Figs. 6 and tween the sleeve 19 and the collar 17, and normally pushes the sleeve outward until the outer surface of the cam 19 is flush with the outer side of the rear wall of the meter base 1 (Fig. 6) the outward movement of the sleeve beinglimited by the pins 19 thereon contacting with the support 1 (see Fig. 6).

A collar 17 pinned fast to rod 16 together with the thumb grip 16" take the end thrust of the rod 16 in both directions preventing its being moved in or out but allowing it to be turned. The thumb grip 16 furnishes a convenient handle by which to turn the rod 16.

The sleeve 19, of course, is manually turned by turning the rod 16. To prevent operation of the register wheels when the meter is removed from the machine, and

until and unless the machine locklOl has been properly unlocked, I provide a third means for engaging and locking the gear 9. This consists of a double arm lever having an upper arm 12 provided with a ioOtll, adapted to mesh with the gear 9 (see Figs. 3, 4, and 8) to prevent turning of the gear or the drive shaft 7 in either direction.

The lower arm 12 is cut with a tooth space 12 and two stops 12 12 Fig. 8) after the manner of an intermittent gear follower and is operated by a tooth 19 on sleeve 19, shifting it from one to the other of its two positions, bringing the upper arm 12 either into or out of mesh with gear 9 as required.

The projecting tooth 19 on the sleeve is designed to operate the lever 12'by engaging the tooth space 12 in the end of the lower arm l2 when the sleeve 19 is in its innermost position (Figs. 4 and 22) and move it according to the direction in whlch the shaft 16 is turned, so that one or the other of the steps 12*, 12 will rest on the cylindrical portion of sleeve 19.

A spring 16 is placed on rod 16 beloo The key 18 is situated within the back wall of the meter and is normally covered and protected by the sleeve 19, which surrounds t when the meter is off the printer (as shown in Fig. 6). This key 18 is constructed to fit but one machine lock 101 so that the meter must be used with the related machine having such lock.

In the bottom of the meter below opening 1 is a hole 1 to receive a bolt 111 which serves to secure the meter in place on the machine, when it is properly applied thereto.

A bolt 110 is preferably mounted on the inside of the wall 100 of the machine to which the lock casing 1 is attached, and when the bolt' is raised its upper end is adapted to enter between the wall 100 and a collar 15 on the meter pin 15 and prevent the latter being projected into engagement with the hole 6 (Fig. 6) in the lever 6. A locking lever 112 is pivoted at 112 on a part 100 of the machine to which the meter is attached :(Fig. 22). As shown, lever 112 has a rounded end 112 engaging an opening in the bolt 110, and this bolt is guided in a suitable opening in the part 100 and in a bracket 114 attached to the part 100 (Figs. 22 and 23). is a toothed segment 112 which meshes with a rack 111 on the bolt 111, which is guided in openings in the part 100 and in the bracket 114, and the upper end of this bolt 111 is adapted to be projected into the hole 1 in the bottom of the meter base 1 (see Figs. 22-23). Bolt 110 is moved up or down by means of the machine lock 101, the cam 113 of lock 101 acting on bolt 110 in exactly the same way as the cam 19 acts on its related bolt 12". Motion is communicated to lever 112 by bolt 110, the bolt 110 being the moving power. When bolt 110 is raised bolt 111 is lowered, until its upper end is flush with the top of the part 100 of the machine upon which the meter is placed. Downward motion of bolt 110 will through lever 112 impart an upward movement of the bolt 111, and vice versa. hen lock 101 is turned to release the meter it raises bolt 110 by means of cam 113, and simultaneously disengages the bolt 111 from the meter, and the meter pin 15 will then be prevented by bolt 110 from engaging the socket in lever 6, as the upper end of bolt 110 enters between the collar 15 and the wall 100. When lock 101 is turned to secure the meter in position the bolt 110 is lowered withdrawing its end from between the shoulder 15 and the wall 100, thus releasing the meter pin 15 and simultaneously bolt 111 is raised into enga ement with the hole 1 in the meter base.

he operation of the combined meter and machine locking devices is as follows: In

pushing the meter into place on the machine the coupling 8 of the meter engages the coupling 102 of the machine (Figs. 4 and On the other end of lever 112 22). The meter rod 15 enters the hole 1 of the meter to within a short distance of the end of the shutter lever 6", and the lock cylinder 101 and its casing 101 enters the hole 1 of the meter, pushing the sleeve 19 inward until the eccentric flange 19 clears the hole 1 and key 18 enters the cylinder 101 of the lock and lines up its pin tumblers (Fig. 22). The rod 16 can then be turned to operate the bolt 111 within the hole 1 in the meter (Figs. 22 and '23), thus locking the meter in place on the machine. It requires one full turn of the rod 16 to so operate the the lock 101, and as sleeve 19 turns with the rod and tooth 19 on the sleeve engages and shifts the catch 12 out of engagement with the gear 9 thereby releasing the meter drive shaft 7 so that it can be turned by the shaft 102 of the printer. The meter is then ready for action, provided it has been set, or charged, as above described.

To remove the meter from the machine the rod 16 is turned in the reverse direction, thereby turning sleeve 19 and causing the return of catch 12 into mesh with gear 9*, the withdrawal of bolt 111 from the hole 1, releasing the meter, and the locking of meter pin 15 so that itcannot reenter the hole 6 in lever 6. The sleeve 19 is also forced outward by spring 16 entering cam 19 in the hole 1"; as inFig. 6.

The meter can then be removed from the machine; but the rod 16 cannot be turned when the meter is removed because the cam 19* being eccentric to the axes of sleeve 19 and rod 16 willbind against the wall of the hole 1 The cam 19 might be pressed into the meter by hand, or other means, while the meter is off the machine, and the rod 16 could then be turned to cause lever 12 to release'the drive shaft 7; but if this should happen by accident, or even be designedly done, the shaft 7 would still be locked by the pawl 10 against any reverse movement and therefore the meter could not be made to alter the count already registered.
